I would like to sincerely express my gratitude to the entire Marine Treasure team for the tremendous contribution this app has made towards helping me clear my Function 1 Oral Examination. The app has been extremely useful, especially for strengthening my understanding of the Rules of the Road (ROR), different practical situations, and the application of COLREGs in various scenarios. The AI-based live oral test feature was particularly helpful, as it gave me the experience of facing realistic oral questions and improved my confidence significantly. Also specially a big thankyou to Captain Ritesh sir and Captain Ayush sir for their incredible support. They patiently cleared numerous doubts of mine and explained different ROR situations and concepts in a very practical and easy-to-understand manner. Their guidance played a very important role in my preparation. Overall, Marine Treasure has been a fantastic learning platform, and I genuinely feel that it contributed significantly to my success in clearing my Oral Examination. Shashank Garg
